Application filed To all whom it may concern:

Be it known that I, EUGENE M. Arman canon, a citizen of the United States. rcsiding at Danville, in the county oi. l /loutour and State of Pennsylvania, have in vented certain new and useful lmprovements in lntake-Bcams, of which the tollowing is a specification.

My invention relates to imprm'cments in brake beams, and more. particularly to an improved fulcrum for brake beams, the object of the invention being to provide an improved single piece fulcrum which will add to, and not detract from, the strength of the beam and which is secured to the beam without the necessity of puncturing the web of the beam.

A further object is to provide a fulcrum of this character composed of a single iu tegral piece of forged metal bent to the desired shape and strong and durable in use.

\Vith these and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts as will be more fully hereinafter described and pointed out in the claim.

In the accompanying drawings: Figure 1. is an edge view showing my imp orcd lul erum on a. beam, the latter shown. in ction, Fig. 2 is a view in side elevation, l ig. it is an inverted plan view of Figjl, and Fig. l is a view similar to Fig. 1, illustrating a modification.

1 represents an ordinary form of Lbeam in common use as a brake beam and on which my improved fulcrum .2 is clamped, as will now be explained.

The fulcrum is composed of a sjn le integral piece of forged metal, bent midway its ends, as shown at 3, to surround and hug the back flanges t of the beam 1. The ends of the metal then extend alongthe sides of the Web of beam 1 and are theubeut beam. The ends of the 'metal are then given a bend, or twist as ehowu at 5 positioning the ends t't'parallel to each other and preferably at an angle of about forty degrees with relation to the beam which is the normal angle the lever (not slit-m n) is to be 1 supported.

Specification of Letters Patent.

Septcmlmr t), 1910. Serial No.

lutcntcd tpr. 25, Hill.

The ends ti are provided adjacent the bends 5 with registering openings 7. 'lior the reception of a rivet s which located in spacing sleeve E). the latter positioned be tween the ends l3 to maintain them the desired distance apart so as not to clamp the lever (not shown) which is lulcrumcd on a bolt (not shown) to be located in registering openings it) in the ends t3.

if desired the base llange 4- of the beam may be crimped at the edges of the 'luldrum. as shown at ill, to prevent any pos ibility of movement oi the fulcrum longitudinally of the beam and other means may be provided, if desired, to prevent such movement, but I do not believe any will be necessary as the t'ulcrum will securely clamp the beam and maintain itself in place.

In Fig. l I show a modification in which the metal olthe fulcrum is bent to lit around a beam ll having but a single llangc 12 at one edge but in other respects the construe tion is identical with that above described and l have used the same reference characters to indicate like parts.

The fulcrum may be bent to [it around any shape of beam and i do not restrict mys'elt' to the precise construction set forth, but consider myself at liberty to make such changes and alterations as lairly tall within the spirit aud scope of the appended claim.

Having fully described my invention what I claim as new and desire to secure by Letters-Patent is In ctnnbination with an angular flanged brake beam, a fulcrum composed of a single integral piece of forged metal bent between its ends to conform to the shape of and surround the beam, parallel ends on said fulcrum bent. at an angle to the bean'i, and one of the flanges of said beam crimped at opposite sides of the fulcrum.

lo testimony whereof l have signed my name to this specification iu the presence of two :nIbst-ribing witnesses.
